Mineral & Land Records System Reports

The Bureau of Land Management (BLM) has developed the Mineral & Land Records System (MLRS) to replace the Legacy Rehost 2000 (LR2000) case management system, Alaska Land Information System (ALIS) (please note that Alaska records are not available in MLRS at this time), and official land status records (e.g. Master Title Plats, Historical Index, Tract Books). 

MLRS is a customer-centric, geospatially-enabled Land Information System that employs nationally standardized business processes, ensuring the quality and accuracy of land and mineral records and data, while securely delivering land records information to relevant BLM employees, customers, and the public.   

The MLRS mining claims module launched on 01/25/2021. Over the next two years, additional MLRS modules will be released in support of land and mineral use authorizations for oil, gas, and geothermal leasing, rights-of-way, coal and other mineral development, land and mineral title, withdrawals, classifications, and other actions on Federal lands or on Federal mineral estate.


Please note that some columns in the MLRS reporting site have changed from the preceding LR2000 output; however, all information previously reported is available.  Last Assessment Year has been replaced with Next Payment Due Date to help users identify when the next assessment year payment is due.


We recommend that you query either all case dispositions or ACTIVE and FILED dispositions for all queries. When claims and sites were migrated from LR2000 to MLRS, any active claims not yet showing that the land status had been checked were set to a “Filed” status in MLRS. A “land status checked” entry on a claim/site indicates that an adjudicator has verified that the land where the claim or site is located was open to mineral location and entry at the time of location. The BLM state office where your claim or site is filed will have to complete adjudication on your claim/site to set the status back to “Active”. When further action takes place on your claim/site or if additional information is needed, you will receive email notification via MLRS and through the postal mail. You can also check MLRS to see if the claim/site has been set to "Active", indicating this step has been completed. Once land status adjudication is complete, your claim/site may be set to “Active”, OR it may be set to “Closed” if your claim/site is on lands not open to mineral location, in which case you will receive notification from the BLM.
